Hey ive a problem with the transparent of a texture.
Its always white instead of transparent.
If I save it as .png it works - but this format isnt supportet, correct?

thats how it looks like in photshop (okay a bit different cause i change the look but anyways)
Doesnt matter whats on the alpha channel its everytime the same: white border .. even if the whole alpha channel is white or black (dont know whats what atm).
